Tylok b-6-dmc-4 Dmc Male Connector 3/8x1/4 Tube Mnpt Brass

Product Description

The TYLOK b-6-dmc-4 is a double ferrule male connector from the CBC-Lok DMC series, designed for use in compression tube fitting applications requiring a secure, leak-tight connection. The fitting connects 3/8 inch OD tubing to a 1/4 inch male NPT (MNPT) threaded port. Constructed from brass, it measures 1.574 inches in length with a 5/8 inch hex for standard wrench engagement. This fitting is manufactured domestically to strict quality control standards and is suited for instrumentation, process, and fluid system installations where reliable tube-to-pipe connections are required. Licensed HVAC techs, plumbers, and instrumentation technicians are the typical installers.

The b-6-dmc-4 is used in residential and commercial applications where compression tube fittings are required to transition between tubing and NPT-threaded pipe ports. CBC-Lok tube fittings are fully interchangeable with Swagelok and Parker A-Lok components. While use of all CBC-Lok components is recommended, intermixing CBC-Lok bodies or component parts with those of other manufacturers will not adversely affect sealing performance. Typical applications include gas, hydraulic, and instrumentation tubing systems that require a dependable tube-to-male-pipe-thread transition.

Key Features

• Double ferrule compression design provides a secure, vibration-resistant tube seal
• 3/8 inch tube to 1/4 inch MNPT end configuration for common tube-to-pipe transitions
• Brass construction offers good corrosion resistance for compatible media
• 5/8 inch hex allows standard wrench installation without special tooling
• Fully interchangeable with Swagelok and Parker A-Lok fittings
• Made in the U.S.A. to strict quality control standards

Compatibility

CBC-Lok DMC series fittings are fully interchangeable with Swagelok and Parker A-Lok double ferrule tube fittings. Intermixing CBC-Lok bodies and component parts with those of other manufacturers will not adversely affect sealing ability, though use of all CBC-Lok components is recommended.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with compression tube fitting assembly. Depressurize and isolate the system before making or breaking any fitting connections. Ensure tubing is cut square, deburred, and fully inserted into the fitting body before tightening the nut. Follow the fitting manufacturer's make-up instructions — typically finger-tight plus a specified fraction of a turn — rather than relying on torque feel alone.
